Question
A 3.50meter length of wire with a crosssectional
area of 3.14 × 10^–6 meter2 is at
20° Celsius. The current in the wire is
24.0 amperes when connected to a 1.50volt
source of potential difference.
Determine the resistance of the wire.

Resistance = (voltage) / (current)
(1.5 V) / (24 A) = 0.0625 ohm.
All that business about the description of the conductor ...
its length, size, temperature, color, price, etc. ... is only
there to distract and confuse us. It's all irrelevant.
